Unda, directed by Anuraga Karikkin Vellam fame Khalid Rahman, tells the story about a group of policemen headed by SI Manikandan played by Mammootty. The team is entrusted with the election duty in the naxal affected area in Chattisgarh. The first look poster was released a couple of days back and it showed a group of policemen fixing a truck's tyre. The producer of the film Krishnan Sethukumar said that Mammootty should be credited for the poster as it had showed even lesser known actors more prominently than Mammootty. Even a debut actor would not have agreed to such a first look poster. Mammootty had put aside his superstar image to bring a totality to the film.
